Slashback: Unenforceability, Conflagration, Cans

This is Slashback for the evening. Please be advised, through the following items, about ... how to turn that extra Pentium into a firewall running iptables; the state of the Symantec patent on software updates (uughh!); more on can satellites, and more.

a filtration system for your 2.4 goldfish Jay Beale points to this followup to his "Why iptables rocks" article of a few weeks ago: "It fulfills my promise to show how to actually build a home/SOHO firewall with Linux 2.4's iptables aka Netfilter. It contains the full code, explained piece by piece, to build a working firewall with 2.4, including all kinds of cool packet mangling for load balancing, redirecting stuff to transparent proxies, or avoiding nmap stealth scans ..."

Out of embarrassment, perhaps? An unnamed correspondent points out this bit of news regarding Symantec's patent on software updates. The upshot is, without pointing out that updating software incrementally is not a patent likely to win them a lot of favor from the industry they have simply decided not to enforce it. Smart move.

Not yet in the can, or the cube either Casey Ho of San Jose's Leland High wrote with some interesting information for those interested in tiny amateur satellites; Leland is one of the handful of schools whose students are designing experimental payloads for inclusion on an upcoming launch.

[We] are focusing on making a CubeSat. Leland High school officially has one satellite to launch, and there are four teams now competing to make a design that will be approved by CalPoly technicians. My own group will attempt to broadcast a powerful long term signal using only a small satellite. The project is not easy since there are a lot of scientific guidelines we must meet. We are discussing how to create a reliable circuit and transmitter that will function in extreme temperatures, vacuum, radiation, and most importantly, after an extra powerful rocket launch. The requirements are available here.

For some of you posters out there, sorry, no living organisms or explosives are allowed on the satellites. ;)"

    The problem is that "things that detonate" ie. true explosives not just pyrotechnical compounds that burn relatively fast (few hundared meters/second as opposed to few kilometers/second) already contain all oxygen they need in they molucular structure. Most pyrotechnical compounds also contain the oxygen they need to burn in some form or another (salt peter [i hope this is the correct english name] is very common oxidizer)

    The problem with explosives (or guns, or other things that go boom) is the fact that pressure is rather low in space which causes all sorts of problems like rather poor and non spectacular burn of pyrotechnics, explosives detonate allright but since there is no medium to carry the shockwave it's not much of fun.

    Sure there are uses for detaching or welding and stuff for explosives in space but using them is FAR from trivial, you need VERY carefull planning for those things to work properly.

Overnight one day, Unisys changed their policy and started cracking down on even free products, and going so far as demand that websites that designed any graphics in .GIF format, employing LZW compression had to pay royalties to them.

      The point is, there's a huge difference between a company publically stating that they don't plan to enforce, and granting an irrevocable royalty-free license to use the patent to the general public. Ten years from now, if Symantec sees their profits starting to dry up, what do you want to bet that this policy will change for the sake of a cash grab. Unlike other forms of intellectual property, such as trademarks (and to a lesser extent, copyright), a company isn't required to enforce their patent to maintain rights over it, and they're fully allowed to change their policies regarding the patents.

    Is that worse than the explosives?

    Instead of using mechanical systems, motors or even explosives (ie. NASA loves exploding bolts - seriously) to deploy fragile solar cells by remote control, in orbit, all you'd need to do is make a nice little bundle of solar cells, coated in this paint, and packaged tightly to prevent damage.

    I'm sure Cassini's controversial nuclear power source was a lot more refined, but it doesn't need to be complicated to work well.
